类似于fft的输出包含零频率项 在转换轴的低阶角, The output, analogously to fft, contains the term for zero frequency in the low-order corner of the transformed axes,因此,freq[0,0]是零频率"术语.换句话说,它是离散傅里叶变换中的常数项.Thus, freq[0,0] is the "zero frequency" term. In other words, it is the constant term in the discrete Fourier Transform. 这篇关于解释numpy.fft.fft2输出的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
